Abstract

A process is disclosed for the physico-chemical treatment of effluent, especially surface water intended for consumption, the process includes the successive steps of coagulation, flocculation and settling, wherein, during the flocculation step, a ballast is introduced into the sludge, the function of which ballast is to make the sludge heavier. The contacting mass used during this flocculation step consists of part of the densified sludge resulting from the settling step and continuously recycled in the flocculation step, without any treatment.
